摘要
用基本子波消失矩的大小刻划了连续子波变换的高频特性．讨论了不同子波变换如果具有相同的消失矩，它们的高频特性是相同的，并且具有相同的衰减率．
This paper describes the charatcrization of high frequency of continuous wavelet transforms, which is based on the number of vanishing moments. Diffrent basic wavelets with the same vanishing moment have the equality characterization of high frequency, and the same decay rate.
